SECRlpEncode
This package is used for SEC blockchain rlp encoding.
- SECRlpEncode
- new SECRlpEncode(config)
- .encode(input, buffer, offset) ⇒ Buffer
- .decode(input, start, end) ⇒ Array
- .getLength(input) ⇒ Number
new SECRlpEncode(config)
new SECRlpEncode(config) Constructs a rlp encode class.
| Param | Type | Description | | --- | --- | --- | | config | TBD | TBD, will be implemented in the future |
Example
const RLP = require('encode.js')
const rlp = new RLP()
SECRlpEncode.encode(input, buffer, offset) ⇒ Buffer
Returns input in RLP encoded format
| Param | Type | Description | | --- | --- | --- | | input | {Buffer, String, Integer, Array} | Input data for RLP encode | | buffer | {Buffer} | Input buffer which is in RLP encoded format | | offset | {Buffer} | Buffer offset position |
SECRlpEncode.decode(input, start, end) ⇒ Array
RLP decode for input data
| Param | Type | Description | | --- | --- | --- | | input | {Buffer, String, Integer, Array} | Input should be in RLP encoded structure | | start | {Integer} | "input" data array starting index | | end | {Integer} | "input" data array ending index |
SECRlpEncode.getLength(input) ⇒ Number
Returns input's length according to the first several indication bytes
| Param | Type | Description | | --- | --- | --- | | input | {Buffer, String, Integer, Array} | Input should be in RLP encoded data, or the returned length is wrong |
中文简介:
本库函数用于SEC区块链的RLP编码 RLP编码用于存储和传输数据,处理数据则用.json格式文件 json文件由RLP编码过以后,由于json文件的键值被去掉了,仅保留内容,因此剩下了大量的空间
主要的函数:
RLP编码: encode(input, buffer, offset) => Buffer 输入"input"可以是{Buffer,String,Integer,Array},RLP编码仅对两种数据结构进行处理:列表及字符串 Nodejs中Array即为列表,其他类型{Buffer,String,Integer}作为字符串处理 该函数的输出结果为RLP编码后的input,类型为Buffer
RLP解码:decode(input, start, end) => Array 输入"input"可以是{Buffer,String,Integer,Array},无论哪种类型,都会被先转换为Buffer类型再进行处理 作用与encode相反,将RLP格式的数据进行解码, 输出为Array类型
获取长度函数: getLength(input) => Number input为经过RLP编码后的数据 函数根据前几个字节的值获取整个input数据的长度
